Tool machine turret high-pressure cutting fluid water guiding device

The invention relates to a high-pressure cutting fluid water guiding device for a utility machine turret for introducing high-pressure cutting fluid into a water inlet of a cutterhead, having a high-pressure cutting fluid not leaking pressure, and also prolonging the service life of the seal ring.

With the rapid development of machine tool technology and materials science and technology, more new equipment and new materials are used in modern manufacturing, and new materials appearing are a major challenge to tool technology. In today's increasingly competitive modern manufacturing industry, all companies want to increase their competitiveness and productivity. However, with the large-scale use of cemented carbide tools, there are more ways to increase production efficiency, and the key point to improve cutting parameters is to control heat; cutting heat affects the formation and discharge of chips, if the temperature is still up to 1000 in the traditional way. The cutting fluid is poured into the cutting zone of °C, and the cutting fluid evaporates immediately, forming a high-pressure steam zone that prevents the flow of low-pressure coolant from reaching the cutting edge. In order to solve this problem, a high-pressure cutting fluid system has been developed for modern machine tools. For example, a high-pressure cutting fluid from a high-pressure pump is introduced into a turret, and is sprayed through a small orifice nozzle to a cutting area between the chip and the rake face of the blade. In addition to effectively reducing the cutting heat in the cutting area and prolonging the tool life, it also increases the chip brittleness and breaks easily, obtaining short chips and eliminating the trouble of frequent shutdown of long winding chips.

The horn portion of the horn can be used to push the sealing portion of the sealing ring, and the liquid pressure or thrust of the high-pressure cutting fluid can be directly obtained from the horn hole portion of the enlarged aperture by the side perforation on the spacer, thereby causing the sealing ring to be in the ring-shaped slot. Produces extrusion thrust energy that is axially displaced outward. The high-pressure cutting fluid water guiding device of the machine tool turret according to the first aspect of the patent application, wherein the pressing surface of the sealing ring is provided with a V-shaped pressing groove; The groove increases the hydraulic force receiving area. In addition to increasing the tight effect of the sealing abutment surface of the sealing ring on the peripheral surface of the inlet of the cutter head, the shape of the groove of the pressing groove increases with the pressure of the incoming liquid. The greater the effect of the large deformation energy, the better the leakage and tightness of the sealing ring can be maintained in the process of passing the high-pressure cutting fluid. The high-speed cutting fluid water guiding device of the machine tool turret according to the third aspect of the patent application, wherein the pressing groove is provided with a spring member for restricting the groove-shaped indentation, so that the pressing groove can be long The stability is maintained or maintained in the shape of a V-shaped slot. The high-pressure cutting fluid water guiding device of the utility machine turret according to the first aspect of the patent application, wherein the water outlet hole of the sealing ring is a tapered water guiding hole with a reduced inner diameter from the inside and the outside, when the high-pressure cutting fluid is When the inside of the water guiding hole is sent out to the water inlet end of the cutter head, the liquid pressure of the high-pressure cutting fluid can be pushed by the wall of the tapered hole of the water outlet guide hole, so that the sealing surface of the sealing ring and the surface of the water inlet hole of the cutter ring are pressed. The contact increases the tightness of the seal. According to the first application of the patent scope, the high-speed cutting fluid water guiding device of the utility machine turret, Wherein, the surface of the cylinder body of the water guiding cylinder is provided with at least one concave ring groove, and the concave ring groove is provided with an O-ring and an annular and radially-expanded spring clip; when the barrel body is assembled into the assembly slot In addition to being able to form a leak stop by the O-ring contacting the hole wall of the assembly slot, the radial elastic force of the spring clip acts to form a positioning on the hole wall of the assembly slot, so that the water guide can be easily assembled in the slot Complete the installation or disassembly on the hole. The high-speed cutting fluid water guiding device of the utility machine turret according to the first aspect of the patent application, wherein the cutting fluid flow path on the casing body of the turret is connected to a pump through a water supply pipe, the water supply pipe There is a waterway control valve on the road, and one end of the waterway control valve has a pressure relief drain end communicating with the water source; the water supply control valve is opened to communicate with the pump through the waterway control valve, and the pumping flow passage can be pumped In addition to the high-pressure cutting fluid input, the switching action of the waterway control valve pushes the high-pressure cutting fluid in the cutting fluid flow channel and the water supply pipe, and the pressure relief is discharged from the pressure-relief draining end to the water source, and the sealing ring is pushed. The lifting action of the high-pressure thrust on the face allows the axial displacement of the seal ring in the ring groove, so that the cutter head rotates to perform the tool transposition process, and the sealing contact surface of the seal ring is in contact with the cutter head. Can reduce or avoid friction loss. The high-speed cutting fluid water guiding device of the utility machine turret according to claim 1, wherein the water inlet of the cutter head of the turret is provided with an inlet matching member, and the outer end of the inlet matching member is opposite to the The size of the outlet hole of the sealing ring is provided with a matching through hole communicating with the inside of the water inlet; a plurality of different diameter water inlets of the existing cutter head on the market, and the assembly of the inlet matching member can be easily matched with the sealing ring. The expected function works. According to the eighth aspect of the patent application, the high-speed cutting fluid water guiding device of the utility machine turret, wherein a matching valve hole is arranged in the matching through hole of the inlet matching member, and a support piece is arranged on the hole outlet of the valve hole. a plurality of the support sheets are provided with the valve holes communicating with the interior of the water inlet a through hole, and a compression spring is supported by the support piece and pushes a steel ball to close the inner end of the matching through hole, and the liquid pressure of the high pressure cutting fluid inside the water guide end is greater than the liquid of the high pressure cutting fluid at the water inlet end When the pressure is applied, the action of matching the through hole can be opened by the steel ball, so that the high-pressure cutting fluid enters the inside of the water inlet through the valve hole to be replenished by the liquid, and vice versa, when the matching through hole stops the feeding of the high-pressure cutting fluid, the compression spring can be used. The rebound force pushes back the steel ball to close the valve to match the through hole, and restricts the high pressure cutting fluid at the inner end of the water inlet to return to the water guide end, avoiding the rotation process of the cutter exchange tool, and the high pressure cutting fluid is sprayed out at the water inlet.
